To all whom it may concern:

Be it known that I, THOMAS J. Goouwiu, a citizen of the United States, residing at Waco, in the county of McLennan and State of Texas, have invented a new and useful Radiator for Automobiles, of which the following is a specification.

This invention has reference to radiators for automobiles, and its object is to provide a radiator which may be readily knocked down or dismantled to facilitate repairs.

Ordinarily automobile radiators comprise two or more series of closely associated pipes or ducts, which after being assembled can only be dismembered with considerable difliculty and the expenditure of a material amount of time. If a leak or some ingury requiring repairs occurs in such a radiator in any part except the exterior portions thereof, there is the necessity of separating the radiator into its component parts and this is only accomplished with relatively great diiiiculty making the repairs to the radiator costly and time consuming. By the present invention the radiator is readily dismantled into a number of large units all parts of each of Which are as readily accessible as the exterior portions of the assembled radiator, Wherefore all needed repairs may be made quickly and with certainty and in ,a very small fractional portion of the time-required for similar repairs to radiators as. ordinarily constructed.

Inv order to accomplish the purpose intended the radiator is made in a suitable number of sections joined together by union connections, so that by the separation of a very few joints the entire radiator is readily separated into a suitable number of large units every part of each of which may be reached Without ditficulty and Without interference from any of the other parts, because the latter are entirely separated therefrom. v v

The construction also accommodates itself to ample radiating space about the Water pipes, and the latter are so proportioned to each other and so arranged that there is an equitable distribution of circulation and this in a far more efiicient manner than occurs in radiators as ordinarily constructed. The circulation is evened up by connecting the front of the crown or. receiving reservoir of the radiator with a header of suitable size connected by down pipes to another header 1 by union connections.

of considerably smaller diameter. The rear of the crown reservoir is connected in a readily removable manner With a header of smaller diameter than the front header and therear header is in turn connected by down pipes to a larger rear header which may be as large as the upper front header. Ordi narily the radiator is provided with an intermediately disposed header connected to the ends of the front and rear headers by unionconnections and the intermediate upper header is in turn connectedby down pipes to a lower header of about the same size, the lower header being in turn connected to the front and rear lower headers In this manner the crown reservoir may be permanently attached to the front radiator section made up of the upper and lower front headers and down pipes connecting them, While the in termediate and rear radiator sections are coupled to the front radiator sections by readily separable union connections and the rear end of the crown reservoir is also connected to the rear radiator section by readily removable union connections. By this arrangement the separation of. a few union connections permits the dismantling of the radiator into a suitable number of radiator sections, each of which is accessible at all points for repairs or Whatever may be needed.

While the invention is particularly adapted for use in connection With automobile radiators, it Will be understood that it may be used in other connections Wherever the features of the invention are applicable.

The invention will be best understood from a consideration of the following detailed description, taken in connection with the accompanying drawings forming part of this specification, with the further understanding that While the drawings show a practical form of the invention, the latter is not confined to any strict conformity with the showing of the drawings, but may be changed and modified so long as such changes and modifications mark no material departure from the salient features of the invention.

In the drawings: Figure 1 is a front elevation of a radiator embodying the present invention, but With the radiator casing omitted. Fig. 2 is an end elevation of the radiator of Fig. 1. Fig. 3 is a section on the rear section, and the section 2 being an' the line 33 of Fig. 2. Fig. 1 is a section on the line 4l4 of Fig. 1. Fig. 5 is a section on the line 55 of Fig. 2.

1n the showing of the drawings no attempt has been made to illustrate the usual hood or casing inclosing the radiator, nor the usual front grating which mayor may not be present, since the invention hasnothing to do with these features, and they are more or less common to different types of automobile radiators.

In the structure shownin the drawings the radiator comprises three radiator sections 1, 2, 3, the section 1 being that at the front end of the radiator, the section 3 being mg therealong is a series oi down pipes 5 ings.

all terminating in'another or lower header 6. The radiator sectlon 2 comprises upper and lower headers 7 and 8, respect1vely,. and

- connecting down pipes 9, While the radiator section 3 comprises upper and lower headers 10, 11, respectively, and connecting down pipes 12.

The top of the radiator is in the form of a crown reservoir ora distributing cham-- ber 13 into which the heated water from the engine is driven through a pipe or duct 1% by the customary circulating pump, the latter, however, not being shown in the draw- The water is returned to the water jacket of the engine by way of another pipe 15 connected to the header 11, this being a customary practice in automobile radiator structures. The chamber 13 is provided with the customary filling neck 16 having the usual screw cap closure 17.

The front end of the chamber 13 is provided with an elongated drop portion 18 made fast to the header i and extending lengthwise thereof and opening into the header through an elongated port or passage 19. Each end of the header a is provided with an elbow 20 and each end of the header 11 has a similar elbow 21, while each header 6 and 10.has respectiveeibow terminations 22, 23. 1

Each header 7 and 8 terminatesin T connections 2-1, 20 alincd with the elbows 20 and 23 and the elbows '21 and 22. Each elbow 201s connected to a respective T 24:

-by a union coupling 26 and other union couplings 26 connect theelbows 23 with the Ts 24 and also the elbows 21 and 22 with the Ts 25.

The header 10 is connected with the rear portion of the distributing chamber 13 through union connections 27, which in the showing of the drawings are two in num her, but it will be understood that one or more may be employed. The chamber 13 is provided with an overflow pipe 28 discharging at a low point and thereby preventing overfilling of the radiator. If it be assumed that the radiator is as full of water as is customary, and the water is being pumped.

through the radiator by the usual circulating pump, and, furthermore, that the engine is running and is being kept cool by the circulation of the water, the l *ated water enters the chamber 13 through i a pipe or duct 11 and under the impulse of ie pump tends to How toward the front of the chamher where it finds escape through the drop 18 and port-19 into the header 1, and gravitates to the header Q, but the pipes 5 and the header 6 being of smaller diameter than the header 4 the water distributes along the header 4 to. all the pipes 5 with more or less uniformity. The resistance offered by the smallness of the header 6 tends to cause the water entering the header 4 to find escape in other directions, and hence water fiows from the header 4 through the elbows 20 to the couplings 2i where the flow is diverted through the header 7 and pipes 9 to the header 8. In the meantime water though in less volume finds its way through the unions 2'? to the header 10 and distributing along the latter gravitates thrpugh the down pipes 12. The water also iinds escape from the header 10 through the elbows 23 to the pipes 9 to the header 8. All the. water from header 7, distributing along the latter in the headers 6 and 8 finds its way to the header lltogether with such water as enters theheader 11 through the down pipes 12 and the water is thereupon'dr'awn from' the. radiator through the outlet pipe 15 to be forced through the cooling jacket of the engine and ultimately returned to the distributing chamber 13. There is thereby produced because of a distribution of resistance to the flow of water and freedom to such flow, an equality of .flow throughout the radiator, so that approximately equal vol;

nines of water are directed through all the radiating pipes of the radiator represented in most part by the down pipes 5, 9 and 12.

Because of this the efliciency of the radiator is very materially increased and the engine is correspondingly maintained in a relatively cool condition.

\Vhen repairs are needed it is only necessary after having removed the radiator from its (rising or hood to disconnect the unions 26 and 27, whereupon the front section 1 isoe acs 4 ing together of a very few union joints and these are all easily accessible from the extenor portions oi the radiator. After the radiator is repaired and reassembled i is then readily reintroduced into the hood or casing and connected up to the pump and engine for use. a
